A Green VNF-FG Embedding Algorithm
2018 4th IEEE Conference on Network Softwarization and Workshops (NetSoft), 2018This paper proposes an Integer Linear Program (ILP) to address the Virtualized Network Function Forwarding Graph (VNF-FG) placement and chaining problem when VNFs are shared across tenants to optimize resource usage and increase provider revenue. Since ILP approaches do not scale well with problem size, the proposed algorithm selects a limited number ...

2018 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2018
With the emergence of 5G and Internet of Things technologies, there is an increasing trend of network services integrating the edge and centralized cloud computing for guaranteeing low latency, real-time processing, and better security/privacy. In this demo, we present an intelligent IoT edge solution with IoT virtual network functions (VNFs) running ...

VNF Service Chaining on SAVI SDI
2015Managing computational resources and networking elements over today’s heterogeneous infrastructure has become very challenging. A need for virtualizing network functions has emerged to reduce infrastructure operating costs. In this paper we consider using software-defined infrastructure (SDI) resource management system (RMS) to achieve service chaining

The fifth generation (5G) utilizes Network Functions Virtualization (NFV) and Software Defined Network (SDN) to provide applications. Among them, there are deadline constrained applications. When the traffic generated by applications traverses Virtual Network Functions (VNFs) chains, it may not be possible to meet the deadlines when the traffic is ...
